Abstract

The utility model relates to a steel and plastic composite material. The utility model is characterized in that the steel and plastic composite material comprises core material and a wrap; the core material is channel steel, etc.; the wrap is plastic or rubber square pipes; the thickness of the wall of a wrap casing is 0.2-5 mm; the bottom width of the channel steel is 10-40 mm, the side height of the channel steel is 5-20 mm, and the channel steel of 20X9 mm is good. Compared with the present theft protection material, because a wrap structure is used, appearance impression is improved, the core material is protected from rustiness, and shape is matched with an aluminium alloy window; the material can be directly arranged on a door leaf or a side window of an aluminium alloy window or an aluminium alloy door to be closely attached with glass, an unsightly iron cage can be completely cancelled, steel is saved by more than 20-40%.

Description

A kind of steel and plastic composite material

The utility model is a kind of steel and plastic composite material.

The existing steel that are used for railing mainly contain round steel or steel pipe, and the steel that particularly are used for the door and window railing mostly are round steel, also are reinforcing bar.For safety at home, people live toward the window of lower building is covered from the outside with reinforcing steel bar cage, because reinforcing bar gets rusty easily, when peeling paint, whole cage just corrosion is full of stains or spots, not only influences impression, also hinder use, relatively serious area also can be therefore and reduction of service life in corrosion.Make anti-theft guardrail for reinforcing bar, also has unreasonable place, the one, the waste steel, the 2nd, the ability of its bend resistance is strong inadequately, theftproof performance is relatively poor, particularly work as municipal administration department and in a single day ban use of this iron cage that hinders the appearance of the city, this material will combine with the alumium alloy door and window of fashion makes just incompatibility, inharmonious of anti-theft guardrail.

The purpose of this utility model be exactly to propose a kind of can be harmonious in shape at color harmony with alumium alloy door and window, theftproof is strong, the novel steel and plastic composite material that can cancel antitheft cage simultaneously, to overcome the shortcoming of prior art.

This steel and plastic composite material that the utility model proposed is characterized in that it has core and jacket, and core is channel-section steel or round steel or i iron or square steel pipe, and jacket is plastics or rubber tube.

Jacket is square tube or pipe.

The quality of fit of canning tube and core is ± 0.1-± 0.5MM.

The wall thickness of canning tube is 0.2-5MM.

Core is good with channel-section steel.

Channel-section steel is bottom width 10-40MM, and the side height is 5-20MM, and inside wall is outward-dipping.

Channel-section steel is with bottom width 20MM, and the side height is 9MM, and the outward-dipping person of inside wall is good.

The utility model owing to adopt wrapping structure, had both improved surperficial impression than existing antitheft material, had played the stainless erosion of protection core again, and shape also adapts with aluminum window.This material can directly be contained on the fan of aluminum window or door or the side window to be close to glass, completely abolishes ugly iron cage, saves steel 20-40%.

Further specify the utility model below in conjunction with example and accompanying drawing.

Accompanying drawing 1 is front view of the present utility model (part).

Accompanying drawing 2 is A-A sectional drawings of the present utility model.

Accompanying drawing 3 is core cross-sectional drawings when being wide up and down i iron.

Among Fig. 1-2.Core (1) is a channel-section steel, and its bottom width is 20MM, the high 9MM of side, and inside wall is outward-dipping.This example only provides a kind of selection of channel-section steel, but it can also comprise round steel and i iron.Jacket (2) is the square tube of wall thickness 1MM, and it cooperates with core, is-0.2 in wide direction, is-0.1 in high direction, is the colored plastic square tube.The area of section of this channel-section steel is equivalent to the round steel of diameter 9.3MM, as the little 22.5-33.7% of the round steel 12-14MM of antitheft cage, the wide 9MM of having only of side of main is this core extremely conforms to the size of the 90 series alloys door-window section bars of using always than usually.Be installed in this material and make anti-thefting strip on the door and window, with comparing of the antitheft cage of employing, no matter be outer choose window or directly be contained in window on the wall eye, each window all can be saved steel 20-40%, the expense of employing plastics jacket is counted also can save cost more than 15%.

Because colored sheath material not only firmly but also elegant in appearance, was extremely coordinated with the size and the color of aluminum window, there is certain flexibility on the surface of sheath material, be close to and can play a very good protection with window glass, so practicality is very strong, through on probation, looked at by user's eyeball.
